Enriching Wikipedia's Intra-language Links by their Cross-language Transfer

Although hyperlinks enhance the utility of Wikipedia, embedding them in articles imposes a burden on contributors. To alleviate this burden as well as enrich hyperlinks in Wikipedia articles, we propose a method for transferring intra-language links between different-language articles linked via an interlanguage link. The method avoids anchor selection and disambiguation problems by which usual wikification methods are affected, by exploiting the analogy between different language editions of Wikipedia. The effectiveness of the method was demonstrated through an experiment of transferring intra-language links from English to Japanese. It increased the number of intra-language links in Japanese articles by 40.9%, and the accuracy of anchors selected was estimated to be 96.3%.
